Abstract

The tests of uniaxial tensile by 10, 20, and 30% at strain rates of 0.1, 1, 60, 120, and 300 mm/min in rolling direction and transverse direction of recrystallized cold-rolled low-carbon steel sheets were carried out. The effect of rate and degree of deformation on the texture, structure, and mechanical properties were studied. The texture transformations and the growth of the anisotropy of mechanical properties with increasing strain rate up to 120 mm/min are explained by the effect of crystallographic intragranular slip and twinning of deformation mechanism. The further increase of deformation rate leads to texture scattering and decreasing of properties anisotropy, which are bound to the difficulty of intragranular sliding and activation of grain boundary sliding.
